Solve the problem.The correlation between respiratory rate and body mass in the first three years of life can be expressed by the function log R(w) = 1.81 - 0.34 log (w),where w is the body weight (in kg) and R(w) is the respiratory rate (in breaths per minute). Find R'(w) using implicit differentiation.
A. R'(w) = -21.95w-1.34 B. R'(w) = 64.57w-1.34 C. R'(w) = -21.95w-0.66 D. R'(w) = -21.95w-0.34
